PowerPoint Presentation: The Reactivity Series potassium sodium calcium magnesium aluminium zinc iron copper gold ( carbon ) Increasing reactivity Metals above carbon must be extracted using electrolysis. Metals below carbon can be extracted from the ore by reduction using carbon, coke, or charcoal. Gold and silver often do not need to be extracted. They occur native.

Oct 11, 2013· Through bustle main hot blast is supplied to the blast furnace through tuyere stock. Carbon blocks – These are refractories made of carbon and are used for lining of hearth bottom and hearth walls. Cast house – This is the area around the blast furnace at the taphole level.

Blast furnace extraction of iron recycling, steel ... Iron is produced (extracted) in a blast furnace by reducing iron oxides with carbon and it is the carbon that removes the oxygen from the iron oxides – the carbon is known as the reducing agent. Coke is a cheap and readily made reducing agent. Get Price

Extraction of Iron in a Blast Furnace The significant reactions occuring within the Blast Furnace can be described via the following steps showing how the reducing agent varies depending on the height in the furnace ( on the Temperature).

Why is limestone added to the blast furnace during the extraction of iron? Iron ore contains the impurities sand and clay, which are silicon oxides. Limestone is added to remove these impurities.

­The more advanced way to smelt iron is in a blast furnace. A blast furnace is charged with iron ore, charcoal or coke (coke is charcoal made from coal) and limestone (CaCO3­). Huge quantities of air blast in at the bottom of the furnace, and the calcium in the limestone combines with the silicates to form slag.

The ore is loaded into a blast furnace along with measured quantities of coke and limestone. Hot combustion air is supplied to the furnace and some form of fuel used to raise the temperature. The iron is reduced from the ore by carbon in the coke, the limestone aiding slag separation from the molten iron.

EXTRACTION OF IRON: The most important raw materials or ores from which iron metal extracted are oxide ores hematite (Fe2O3) or limonite (Fe2O3. 3H2O). The first stage involved in the manufacture of iron is the reduction of oxide ores in a blast furnace as given in fig. This involves the crushing of the oxide ore to produce lumps.
